  However, when defrosting the cooler in the conventional configuration, the defrost heater is generally energized until the frost formation on the cooler is removed. Fermentation of bread dough, when thawing very delicate bread dough in a temporary storage or slow thawing at low temperature, the temperature in the storage can be below 5 ° C where fermentation does not progress, and it can be thawed at a low temperature – a narrow temperature control above 5 ° C is required In general, when defrosting is performed at an internal temperature of 0 ° C used for bread dough, the temperature becomes 5 ° C or more temporarily, and the surface of the dough is damaged, greatly affecting the quality of the finished bread. Had.

  The present invention solves the above-described conventional problems. When the inside temperature is about 0 ° C. and the defrosting is performed during low temperature thawing, the inside of the inside is kept at 5 ° C. or lower where fermentation does not proceed regardless of the amount of frost formation. An object of the present invention is to provide a cooler defrosting device for bread dough fermentation and thawing that can reliably defrost the cooler while keeping it, and does not impair the bread dough.

  In order to solve the above-mentioned conventional problems, the defroster of the bread dough fermentation and thawing cabinet of the present invention includes a refrigerator for fermenting, thawing and temporarily storing the dough, and a cooler provided in the warehouse. A compressor for cooling the interior using the cooler, a condenser, a heater for heating the interior, a fan for agitating the interior, and the cooler A drain pan for receiving drainage, an internal temperature detection means for detecting the internal temperature, a cooler temperature detection means for detecting the temperature of the cooler, and the internal temperature detection means Consists of an arithmetic processing unit that is controlled by the value obtained from the cooler temperature detection means, and uses a heater used in the defrost fermentation to bring the internal temperature to 0 to 3 ° C and the cooler temperature to 0 ° C. The air is raised and heat is exchanged between the cooler and the internal air using a fan.

  The frost in the cooler melts, and the internal temperature prevents a sudden temperature rise due to latent heat of melting. When defrosting, the temperature becomes 0 ° C or higher, and the internal temperature starts to rise. This phenomenon is caught by the internal temperature detection means and the cooler temperature detection means, and the defrosting is completed. At this time, the drain pan is also heat-exchanged with the inside temperature to maintain the plus temperature, and receives the molten water (drain water) and drains it outside.

  As a result, when the inside temperature is kept at around 0 ° C and defrosting is performed during low temperature thawing, the defrosting of the cooler is ensured while keeping the inside at 5 ° C or below where fermentation of bread dough does not proceed regardless of the amount of frost formation. Can be done.

  The cooler defroster of the bread dough fermentation and thawing cabinet of the present invention is temporarily stored at a temperature of about 0 ° C., and when defrosting is performed during low-temperature thawing, the fermentation does not proceed regardless of the amount of frost formation. By keeping the inside of the cabinet, it can be defrosted without causing any damage to the dough.

(Embodiment 1)
FIG. 1: shows the block diagram of the cooler defrosting apparatus of bread dough fermentation in Embodiment 1 of this invention, and a thawing warehouse. FIG. 2 shows a flowchart of the cooler defroster of the bread dough fermentation and thawing cabinet of the embodiment.

  In FIG. 1, the interior 2 is for fermenting, thawing and temporarily storing the bread dough 1, and the outer shell is composed of a door 4 for taking in and out the bread dough and a heat insulating material 3 for insulating the interior.

  In order to cool and heat the interior 2, a cooler 5 and a heater 8 are installed in the interior 2. The cooler 5 is connected to a compressor 6 and a condenser 7 to form a refrigeration cycle.

  The inside 2 has a fan 10 for circulating air, a tray 10 on which the bread dough 1 is placed side by side, and a tray rack 11 for receiving the waste water in the inside 2 including the drainage of the cooler 5 and discharging it to the outside. A drain pan 12, an in-chamber temperature detecting means 13 for detecting the temperature of the inside 2, and a cooler temperature detecting means 14 for detecting the temperature of the cooler 5 are installed.

  A relay A15 is installed to turn the compressor 6 on and off, and a relay B16 is installed to turn the heater 8 on and off. The relay is a value obtained from the internal temperature detection means 13 and the cooler temperature detection means 14. It is comprised by the arithmetic processing part 17 which controls A15 and relay B16.

  The operation of the cooler defrosting device for the bread dough fermentation and thawing cabinet configured as described above will be described below with reference to FIG.

  In FIG. 2, when the amount of frost formation in the cooler 5 increases during thawing or temporary storage at an internal temperature of about 0 ° C., the cooling capacity decreases. Therefore, defrosting control is entered in STEP1.

  In STEP 1, the cooler end temperature a (5 ° C. or lower) at which the defrosting ends is substituted for the defrosting end temperature A.

  In STEP2, the relay A15 is turned off, the compressor 6 is stopped, the relay B16 is turned on, and the heater 8 is heated.

  If the value T of the in-chamber temperature detection means 13 is T ≧ 3 ° C. and the value t of the cooler temperature detection means 14 is t ≧ 0 ° C. in STEP 3, return to STEP 4, otherwise return to STEP 2 to satisfy the condition of the heater 8. Until heated.

  In STEP 4, the relay B16 is turned ON / OFF, and the value T of the internal temperature detection means 13 is controlled to be T = 3 ° C.

  Since the air of about 3 ° C. is circulated by the fan 9, the frost of the cooler is melted by exchanging heat with the cooler 5. In addition, the internal temperature prevents sudden temperature rise due to latent heat of fusion.

  When the defrosting is performed, the value t of the cooler temperature detecting means 14 becomes a value higher than 0 ° C., the temperature T becomes substantially the same as the value T of the internal temperature detecting means 13, and both begin to rise.

  In STEP 5, the value t of the cooler temperature detection means 14 is compared with the defrosting end temperature a. If t ≧ a (5 ° C. or less), the defrosting is completed and the relay A15 is turned on in STEP6 and the compressor 6 is operated. It cools to the predetermined | prescribed internal temperature and is complete | finished.

  Thereby, irrespective of the amount of frost formation of the cooler 5, it can defrost without giving a disorder | damage | failure to dough by keeping the inside of 5 degreeC or less which fermentation does not always advance.

  As described above, the bread dough fermentation and defroster defroster according to the present invention can be defrosted while taking into consideration the storage temperature of the food, and therefore can be applied to uses such as a defroster and a partial store.
